It's simply a wedge of wood, but that's not a bad thing!
I've grown up using the soft gel wrist rests, and wasn't expecting to like something as rigid as a wooden rest. But I was drawn to the aesthetic of the wood grain and got this in spite of my misgivings... and I like it! It makes an impression wherever I take it, which is another surprising thing I didn't I'd be doing with this rest--I throw it in my backpack and take it around with me sometimes! I will agree that the actual shade of the Ugyen wood is much darker than what appears in these official photos--like a black walnut wood finish. Just keep that in mind if you're trying to color match.
I like the rest, but I found that when something fell on it, it chipped rather than dented. I also found that the finish that was used has started to show it's age.
Overall, it's cheap enough where I wasn't super concerned, but I can't give it full marks. The material choice for the finish just wasn't what it needed to be.
